AN AWARD win­ning project at the Biggen­den Sew­er­age Treat­ment Plant has drawn in­ter­est from an In­done­sian Lo­cal Gov­ern­ment.

They are look­ing at a sim­i­lar project that would cover 85ha and ser­vice one mil­lion peo­ple.

At the re­cent In­sti­tute of Pub­lic Works En­gi­neers Aus­tralia (IPWEA) State Con­fer­ence the North Bur­nett Re­gional Coun­cil was awarded the 2014 En­gi­neer­ing Ex­cel­lence Award for projects un­der $1 mil­lion.

NBRC tech­ni­cal ser­vices man­ager Trevor Har­vey dis­played the awards at Tues­day’s gen­eral meet­ing at Biggen­den.

Ac­cept­ing the award, act­ing mayor Cr Faye Whe­lan said the team needed to be con­grat­u­lated.

“You should be very proud of your ef­forts with this in­no­va­tive idea,” Cr Whe­lan said.

Mr Har­vey said the up­grade in­volved the re­newal of var­i­ous sec­tions of the 40-year-old plant, along with the con­ver­sion of the third la­goon to a sub­sur­face rock fil­ter.

“The project was com­pleted on time and un­der bud­get with about 70% lo­cal and re­gional labour con­tent,” he said.

“The orig­i­nal project scope en­com­passed an up­grade of all el­e­ments of the treat­ment plant to de­fer the re­quire­ment of con­struct­ing a new plant in four years’ time.

“The re­sults since bring­ing the plant on­line have shown ex­cel­lent wa­ter qual­ity, no in­crease in power con­sump­tion and a re­duc­tion in chem­i­cal ad­di­tion.”

The project is ex­pected to elim­i­nate the need for a new plant at a pos­si­ble sav­ing of up to $4 mil­lion to coun­cil.

The re­sults of the sub­sur­face rock fil­tra­tion have led to other lo­cal gov­ern­ments both in Queens­land and over­seas plan­ning to use the fil­ters.

Mr Har­vey has also pre­sented four pa­pers on the rock­fill fil­tra­tion.
